Principle Of Sound Intensity Measuring Instrument

Ultrasonic sound intensity power meter is mainly used in ultrasonic cleaning machine, measuring the intensity of ultrasonic unit area in ultrasonic liquid, judging the quality of ultrasonic equipment by intensity, and the ultrasonic intensity (sound power) in the sound field of stable liquid is one of the most ultrasonic systems. The main indicator. It has a direct impact on the cleaning effect of the washing machine and the working efficiency of the ultrasonic processor. The sound intensity meter measures the sound field strength quickly and easily anytime and anywhere, and intuitively gives the sound power value.

Depending on the application, the ultrasonic power tester can be made portable and on-line.

Principle of ultrasonic sound intensity measuring instrument

The sound intensity measuring instrument uses the positive piezoelectric characteristic of the piezoelectric ceramic, that is, the piezoelectric effect. When we apply a force to the piezoceramic, it converts the force into an electrical signal. Under the same conditions, the stronger the force, the higher the voltage. If the magnitude of the force changes at a certain period, the piezoelectric ceramic outputs an AC voltage signal of the same frequency. Due to cavitation and other disturbances, the actual voltage waveform is a superposition of a main wave and many secondary waves. The precision ultrasonic frequency (energy) analyzer of our company's sound field can intuitively observe the actual action waveform and read the sound intensity value.

Ultrasonic cleaning, ultrasonic sonochemical treatment, ultrasonic descaling, ultrasonic dispersion and pulverization, etc. are all carried out in a certain liquid. The ultrasonic intensity (sound power) in the liquid sound field is one of the most important indicators of the ultrasonic system. It has a direct impact on the use of ultrasonic equipment and work efficiency.

The ultrasonic power (sound intensity) measuring instrument can measure the sound field strength quickly and easily anytime and anywhere, and intuitively give the sound power value.

Its characteristic is that it does not care about the power of the sound source, and only cares about the actual intensity of the ultrasonic wave at the point where it is measured. This is the data that should be concerned. The sound intensity measuring instrument also has a real-time signal output interface. If the spectrum analyzer is used, the frequency can be measured without measuring, and the distribution and intensity of various ultrasonic resonances can also be measured and analyzed.
